Woah, now here's a juicy rumor to start your Thursday morning off with. BGR reports word from multiple trusted sources that RIM intends to take its BlackBerry Messenger outside the cozy confines of the BB ecosystem and straight into its competitors' app stores. BBM is reputedly all set to make its debut as a messaging app on both iOS and Android, though the specifics of what it might cost you have yet to be ironed out. It'll come in a stripped down version, you'll still need to own a BlackBerry for the full-flavored BBM experience, but that should nonetheless be extremely welcome news for folks finding themselves torn between platforms. The Android version is expected this year, say the sources, while the iOS app may take a little while longer thanks to Apple's more capricious approval requirements.
